Abstract
A drilling machine with an automatic tool changer (A.T.C.) comprising a driving motor for a spindle head and a tool magazine rotatably supported by the spindle head and provided with a plurality of tool arbors for holding tools, one of the tools being interchanged with another of the tools by intermittent rotation of the tool magazine, and wherein the tool arbors are supported for swinging movement between a protrusion position and a retraction position so as not to obstruct the machining operation.
Claims7
A drilling machine with an automatic tool changer comprising longitudinally traversable spindle head including driving means therefore;
- a spindle rotatable held by said spindle head;
- a bar one end of which is slidably supported by said spindle head;
- a tool magazine which is intermittent-rotatably supported by the other end of said bar;
- a plurality of tool arbors for holding tools, rotatably held by said tool magazine, each of said tool arbors being detachable from said spindle and driven to rotate by said spindle;
- wherein the improvement comprises a cam plate fixed to said bar, and a plurality of support rings for rotatably supporting said tool arbors, each of said support rings being swingably attached to said magazine and having means engaging said cam plate and being supported for swing movement in the tool magazine between a working position in which the tool arbor is aligned with the axis of said spindle and a non-working position in which the tool arbor is retracted responsive to relative rotation between said magazine and said cam.
